the water pump went out in my dx, i rode it for a few weeks cause money was not good, it overheated a couple of times before i could get it fixed, well, i changed out my water pump and timing belt, and put on a new valve cover gasket, and two hours after i had it running i cracked the head gasket. the heads were warped, i sent them off to get shaved and cleaned up, what are the chances of my bearings being bad to where i need a new motor. i had my mechanic mention something about them being bad. also i want to know which is better h22 or b16a. i know h22 is heavy and if i took a turn doing 70 on the freeway, i would underturn and go into the ditch. so...help please!
